Valoya RX400 is a high‑power LED toplight for greenhouses and single‑tier rooms. Typical power draw is 395 W with 0–10 V/PWM dimming, and spectra options include AP67 and NS1. The 2024 RX‑series tech sheet rates RX400 up to 920 µmol/s (spectrum dependent) with efficacy around 2.2–2.3 µmol/J. The sealed, passively cooled aluminum housing is wet‑location rated (IP65) and built with a tempered‑glass cover. Fixture dimensions are 347 x 382 x 166 mm and weight is about 11 kg. Recommended mounting distance is 0.5–4.0 m above canopy with a 120° beam. In Solray testing, a 1.2 x 1.2 m footprint at 0.5 m delivered roughly 450 µmol/m²/s central PPFD. Typical lifetime is 50,000 h (Q70/L70), with Q90/L90 around 36,000 h.
